when I first found ham radio, this is what I found
10M was empty
20M was for contacts only, very little talking about anything
40M had people that had actual conversations
80M had people that talked lots, I mean they talk for 5 to 10 min. and then turn it over to the next in the group, would take them 30 min. to an hour to get back to the first person, and they did this daily for at least 20 or so years before I found them, and there are many groups of them all over the band
never could get a 160M antenna up to find out what was there, but I do know that historically this band was used like the 2M band is used now
now I have a 40M only antenna (NVIS)
would like more bands, or even a regular 40M antenna,
guess I have to work harder to get them set up
